01Overview of Screen Technology
◆ Basic structure of capacitive touch screen
In the evolution of touch screen technology, we have witnessed the competitive landscape from IPS, AMOLED, SLCD to OGS, while also witnessing the rise of In cell and n-cell technologies. In order to gain a deeper understanding of the three screen technologies of In Cell, On Cell, and OGS, we first need to analyze the basic structure of the screen. The structure of a capacitive touch screen is divided into three layers: the top layer is a glass cover plate, which is responsible for protecting the screen and transmitting tactile sensations; The middle layer is a capacitive touch layer, responsible for sensing and responding to touch signals; The bottom layer is the display panel, responsible for presenting images and colors.
The capacitive touch layer is composed of an ITO touch film layer and an ITO substrate. The display panel consists of an upper substrate, a liquid crystal layer, and a lower substrate from top to bottom. In the early days, frame pasting technology created a layer of air between the touch layer and the display panel, which affected the display effect. However, by using full lamination technology to eliminate this layer of air, the reflection problem of the screen has been significantly improved, making it more transparent when lit up and darker when turned off, eliminating the gray and white appearance.
Differences in Traditional Screen Structure
Traditional G/G and GFF screens both follow a similar structure: cover glass, touch layer, and display panel. But the difference in touch layer is the key to these two screens. Specifically, the structure of G/G and GFF screens is similar, with the main difference being the touch layer. The touch layer of G/G screens consists of one layer of ITO substrate and one layer of ITO touch film, while the touch layer of GFF screens consists of two layers of ITO substrate and two layers of ITO touch film (named ITO: X and ITO: Y respectively). Obviously, G/G screens have an advantage in thickness.

Comparison of Emerging Screen Technologies
Nowadays, OGS screens are favored by touch panel manufacturers, while In Cell and On Cell screens are highly regarded by display panel manufacturers such as Apple LG、 Samsung and Sharp, among others. Both of these screen structures have abandoned the traditional touch glass layer, thus achieving a thinner and lighter design. However, the key difference between the two lies in the integration position of the touch layer. Specifically, the OGS screen uses the same glass to achieve touch functionality; In Cell embeds the touch film layer into the display panel; On Cell places the touch film layer on top of the upper substrate. This difference affects screen design and performance.

02Comparison of In Cell, On Cell, and OGS
◆ Display effect differences
OGS screens perform better than In Cell and On Cell in terms of transparency and visual effects. Therefore, although well-known brands such as Apple and Samsung use In Cell screens, their simple screen transparency and visual effects are not superior to some domestic phones that use OGS screens.
◆ Lightweight and impact resistant
In terms of lightness and thinness, In Cell stands out with its lightweight and compact features. In Cell is the lightest and thinnest due to the integration of the touch layer into the display panel, which is also one of the reasons why iPhone can maintain its lightness and thinness even with a metal body. In contrast, OGS and On Cell are slightly inferior in terms of thinness. In terms of screen impact and drop resistance, On Cell performs the best, followed by OGS, while In Cell is relatively weaker. It is worth noting that OGS, by combining the cover glass with the touch layer, may weaken the strength of the glass during the processing, making the screen relatively fragile.

◆ Touch effect and technical complexity
OGS screens have higher sensitivity, while In Cell and On Cell interaction have lower sensitivity, but rely less on touch chips. High sensitivity may also bring problems, such as "screen jumping" phenomenon, which may be caused by fine dust, sweat or water vapor leading to misoperation of the touch screen. In contrast, in Cell screens directly integrate touch and liquid crystal layers, resulting in higher sensing noise and requiring specialized touch chips for filtering and correction. OGS and On Cell screens have relatively low dependence on touch chips.

Production cost and yield rate
From a technical perspective, the technical complexity of In Cell and On Cell is higher than OGS, and the difficulty of production control also increases accordingly, leading to an increase in manufacturing costs. In terms of yield, the initial production yield of In Cell screens was relatively low, which affected the supply of iPhone 5. But with the continuous technological investment and process improvement of manufacturers, In Cell technology was once affected by low yield rates, and now the yield rate has increased, approaching On Cell and OGS.

Overview of Screen Materials


With the popularity of mobile phone color screens, the choice of screen material has become increasingly crucial. The differences in color screens of mobile phones mainly stem from differences in LCD quality and research and development technology, leading to the emergence of several major screen materials, including TFT, TFD, UFB, STN, and OLED. Usually, the more colors that can be displayed, the more complex images can be presented on the phone, and the levels of the screen are also richer.



TFT-LCD characteristics


TFT-LCD liquid crystal display screen, also known as thin-film transistor type liquid crystal display screen, is known as the "true color" display technology. Its uniqueness lies in equipping each pixel with a semiconductor switch, allowing each pixel to be directly controlled through point pulses, thereby achieving higher reaction speed and color accuracy. Therefore, TFT LCD displays not only have excellent brightness and high contrast, but also have a strong sense of hierarchy and bright colors. Despite its drawbacks of high power consumption and high cost, TFT LCD technology still drives the rapid development of mobile phone color screens. Nowadays, many new generation color screen phones support displays of up to 65536 colors or even 160000 colors, which undoubtedly demonstrates the significant advantages of TFT LCD in color richness and contrast.



IPS Technology Improvement


In addition, IPS technology is also worth mentioning. This technology is not a new screen material, but an improvement of LCD technology developed by Hitachi in Japan. By changing the arrangement of TFT liquid crystal molecules, IPS screens not only have a larger viewing angle, but also almost no ripples appear when pressed, resulting in higher color reproduction and more realistic images. It is worth mentioning that IPS displays perform well in handling highlight issues. After the transistor on a regular display screen burns out, it will produce bright spots, while IPS screens can transform it into dark spots without light, thus avoiding interference during viewing. Therefore, when choosing a screen, IPS screen is undoubtedly a recommended choice.



Advantages of AMOLED


AMOLED， Active Matrix/Organic Light Emitting Diode is an active matrix organic light-emitting diode that has the ability to emit light autonomously. It inherits many advantages of OLED, such as fast response, high contrast, wide viewing angle, and lightweight features. In addition, due to the inherent luminescence of AMOLED, its power consumption is only 60% of that of traditional screens, making it very suitable for use in mobile phone screens. When displaying dark colors, its luminous brightness is low, further saving energy.

At present, Samsung is a leading enterprise in AMOLED technology and holds the core technology. With numerous inherent advantages, AMOLED is expected to dominate the screen market in the future. However, due to production capacity limitations, Samsung is unable to meet the needs of all customers. For example, the iPhone 4 was originally planned to use an AMOLED screen, but ultimately switched to an IPS screen due to insufficient production capacity.



Enhancement of Super AMOLED


On the other hand, Super AMOLED, as an upgraded version of AMOLED, further optimizes the screen structure. It removes the touch sensitive panel in the middle and integrates touch functionality directly onto the AMOLED display layer, making touch more sensitive and color rendering more vibrant. In addition, the design of the native touch panel also improves the transparency of the screen, making the display effect more outstanding. Therefore, Super AMOLED surpasses traditional AMOLED screens in terms of touch sensitivity and display performance.



It is worth mentioning that Super AMOLED technology also incorporates two touch technologies, oncoll and incell. Among them, the oncell technology embeds the touch panel function between the color filter substrate and the polarizing plate, simplifying the production process. Although the production yield of incell technology still needs to be improved, its design concept of directly integrating touch panel functions into LCD pixels undoubtedly brings more possibilities for future screen technology.



Comparison of different materials


Compared with TFT screens, AMOLED has the characteristics of faster response speed, higher contrast, wider viewing angle, and thinner and lighter. In addition, due to the inherent luminescence of AMOLED screens, their power consumption is only 60% of that of TFT screens, making them very suitable for use in mobile phone screens. With the continuous maturity of AMOLED technology, we have reason to believe that it will be widely used in more mobile phones.



In the comparison of various screen materials, STN screen was the main component of early color screens, initially only able to display 256 colors. Although it can display 4096 or even 65536 colors after technological improvements, the common STN screens on the market still mainly use 256 colors. The advantages of STN screens are low cost and low energy consumption.



TFT screens are known for their excellent brightness, contrast, and layering, as well as vibrant colors, but their drawbacks are high power consumption and relatively high cost.



The UFB screen is designed specifically for mobile phones and PDAs, featuring ultra-thin and high brightness, capable of displaying 65536 colors, and a resolution of up to 128 × 160. Its special grating design reduces pixel spacing, thereby improving image quality. The UFB screen combines the advantages of STN and TFT, with lower power consumption than TFT and a price comparable to STN.
